2018 MERCEDES-BENZ AMG C43 Complaints
I was driving around my neighborhood one day with my panoramic sunroof open and at the red light i wanted to close the sunroof (california summer sun is no joke) and it made this really big 'THUMP' noise, thought the sunroof glass cracked. After the big THUMP noise, the sunroof wouldnt close and this is after the light turned green so i am driving slowly because there was rattling noise coming from the sunroof and didnt want the sunroof to fly out from the car. So i had to pull over and try to figure out if its okay to drive with stuck sunroof with it rattling noise. after that i tried to close and open the sunroof and wouldnt move or do anything, it was just stuck. So i turned my hazzards on then drove slowly back home. after about 30 mins playing with sunroof in my garage, hoping that i will close (then at least i can still drive my car without being scared that it will fly out from my car), finally go it to closed but now it doesnt work at all. then i have found out that from 2014 to 2018 pano sunroof is known issue and there were safety recall on some pano sunroof already on this model. i called 6 places and they told me (besides from how many they had already repaired) the holder on the sunroof rail is broken so the whole rail assy needs to be replaced. imagine if i was on a freeway going 65+ and if this would have happend and this HUGE pano sunroof flew out from my car... this is very big safety issue and that probably why 2017 (same pano sunroof) was on a recall.;
2018 MERCEDES-BENZ AMG C63 Complaints
I have a 2018 Mercedes Benz c63 amg which I purchased new in 2018. I have only 61,230 miles yesterday 11/10/2025 it started making a loud noise coming from the right rear. I drove to the Mercedes dealership in Belmont,Ca the technician mechanic told me that the rear differential was bad and need to be replace. Cost $7,000. I don't understand only 61,230 miles why did it go out so soon I always had the maintenance done. My warranty has expired. I did some research and found that there was a recall for 2018 Mercedes Benz c63 amg related to the rear differential. The recall was issued due to potential issues with the rear differential that could lead to a loss power to the rear wheels, increasing the risk of a crash. Owners were advised to contact their local dealerships for repairs or replacements as necessary.;
